Formosa Advanced Technologies Co., Ltd. — AI supply-chain exposure

Formosa Advanced Technologies is a back-end test-and-packaging house inside the Formosa Plastics group, handling the wafer probe, final test and module assembly that turn raw DRAM into shippable memory. Its work sits downstream of Nanya Technology, whose output it is closely tied to, placing it in the unglamorous but necessary final stretch of the memory chain.

The model weights it lightly. It is a capacity provider in testing, not a designer or a fabricator, so its fortunes track the memory cycle it serves rather than any independent pricing power. Its relevance to AI is derivative: it rises and falls with the DRAM demand that stacked memory pulls through the chain.
